The new PS4 controller design, which remains a closely guarded secret across the PlayStation organisation, is expected to break new mould for Sony. The biometric tech, in particular, is something games studios such as Valve are interested in due to its function as a heart beat sensor.

Sony is trying to change the way you think about user accounts with the PS4. As it stands now, and this applies to all current consoles the PS3 (and the Wii U), when you log in, you log in as a single user. With Orbis, Sony is moving the place of "ownership" away from the console, with something it calls "multi-user simultaneous logins."

Which means that the PS4 will let more than one person be logged into the same system at the same time. It achieves this by linking control pads to user accounts; as each new controller syncs with the system, that player's account can be logged in as well. Accounts won't be "locked" to a controller; you'll simply be prompted to sign in to an account every time an extra pad is connected to the console.
